摘　　要：实验室合成了一种阳离子型双子表面活性剂,记作14-4-14。对合成产物进行了结构表征和理化性能测定。结果表明,合成产物即目标产物,并且具有优越的表面活性。在此基础上,研究了14-4-14对大港油田原油-水体系表面张力的影响。结果表明,该产物能有效降低原油-水体系的界面张力,可以将界面张力降低到10-4数量级,适合做表面活性剂驱油剂。An cationi gemini surfactant denoted 14-4-14 was synthesized in laboratory.The properties of the product were characterized and the physical and chemical properties were determined.The results show that the synthetic product was the target product with the superior surface activity.The interfacial tensions between crude oil from Dagang Oil Filed of China and 14-4-14 solution were measured,the results show that 14-4-14 is effective in lowering crude oil-water system interfacial tension and the interfacial tension can be reduced to 10-4 orders of magnitude,whichi is suitable for surface active agent flooding.
